txt.png Singularity-Paper

Yesterday I published my paper about Singularity on paper.kickino.org.
Singularity is a Microsoft research project. I wrote some notes about Singularity in an earlier blog entry.

The university marked it (together with a presentation) as 2.0. :-)

These days I played a little bit around with Nagios, which is able to check several hosts and services. With the support of a free vServer of EUserv I did a setup of such a system.

My highlight is that a downtime of a service will notify me via Twitter. Furthermore the Gentoo Nagios guide helped my very much. There exist several Nagios plugins to check ssh, jabber, irc and other tcp ports and many other things to monitor.

If somebody knows a free Nagios infrastructure I'll be interested in this. :-)

Chemnitzer Linux Days 2009

The last days I was on the Chemnitzer Linux Tage 2009. It is a big event, where the open source and free software community meet each other. There you've get the chance to ask your questions and get in touch with GNU/Linux and the distributors.

There were a lot of talks of several difference topics. But don't forget the social part of such events. I met several people, I never met before in real life. It was really fantastic.
If you would like, you could have a look at my pictures of the CLT09.

CVS available

Because of a note of KillerFox, I decided to put prim-test into a CVS repository. So now you can easily check out this stuff.

To get anonymous (read only) access to the project, you need simply:

export CVSROOT
cvs co prim-test

To set up a CVS server, I used this Gentoo Howto. In the near future I will put some other stuff under version control, too.

cpp.png prim-test

During the last days I programmed a little bit around on a very old project I never finished. It's a little game. Someone gives you a number and you have to decide if it is a prime number or not. I called it prim-test.

It's very easy and you can check if you've got special feelings on prime numbers like a few other guys. The programm will dice everytime to choose if it will print a prime number or not. In the end you've got your points and a percentage of your right answers.

Have fun with it. :-)

Yesterday I listened to the podcast Bits und so #135. There was a little chapter about an really interesting application: f.lux.
It changes the temperature of your screen colors to be like the naturally light of the day or the night around you.

I tried it, and I find the colors really warm and they're not as bright as before. So I believe it will help me to work better in the hours of an evening or afternoon.

For all German readers: Golem published an article about f.lux, too.

I am certificated

Yeah! I've done a short test on the site of the German Telekom about some basics in German, English, IT stuff, maths and economics. And what should I say? Now I am certificated. :-)

Really nice this sheet of paper. I wonder what I could do with it. Well... let's see. ;-)
